The choice itself was simple — remain or leave — but the reasons were not.

The "leave" camp is concerned with an issue quite familiar to Americans — immigration. They said an influx of immigrants over the last few years has damaged Britain’s economy, so leaving the EU would allow Britain to "regain control of our borders.” (This sounding familiar yet?)

Meanwhile, the "remain" camp argued that leaving the EU posed a worse threat to the economy than immigrants ever could. More exactly, they said dipping out could cost Britain hundreds of thousands of jobs, and billions of pounds.

There's also been a fairly-strong age divide among the electorate — much like America’s Democratic party. Older voters (think: Hillary Clinton supporters) supported leaving the EU, while younger voters (think: Bernie Sanders fans) were in favor of staying.

And much like our current Republican candidate, the issue is so divisive it even split the majority party in two. Prime minister David Cameron supported remaining in the EU, while his likely successor, former London mayor Boris Johnson, wanted out.
